WATER-FILTER.

SPECIFICATION forming' part of Letters Patent No. 611,426, datedSeptember 27, 1898.. Application tiled November l2, 1897. Serial No.658,309. (No model.)

- Be it known that we, DWIGHT J. Buss and EDWARD J. RICHMOND, citizensof the United States, residing at Carthage, in the county of Jasper andState of Missouri, have invented certain new and useful Improvements inWater-Filters; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. ,l

Our invention relates to a novel form of filter, and the object is toprovide a simple, inexpensive, and effective filter for general use thatshall be automatically cleaned each time a quantity of water is drawnfrom the filter.

To these ends the invention consists in the construction, combination,and arrangement of the several parts of the device, as will behereinafter more fully described, and particularly pointed out in theclaims.

The accompanying drawings show our invention in the best form now knownto us; but many changes in the details-might be made within the skill ofa good mechanic without departing from the spirit of our invention asset forth in the claims at the end of this specication.

In the accompanying drawings the saine reference characters indicate thesame parts.

Figure 1 is a perspective view of our improved filter. Fig. 2 is a frontelevation with a portion of the casing removed to show the cleaningdevice. Fig. 3 is a vertical section.

' Fig. 4 is a horizontal section on the line 4 4 of Fig. 3. Fig. 5 is asimilar View 'on the line 5 5. Fig. 6 is a vertical section through thevalve-casing, taken at a right angle to that shown in Fig. 3. Fig. 7 isa detail view of the plug cock or valve removed from the casing. Fig. 8is a detail view of the spring-pawl.

1 represents the cylinder or casing, and it may be of any size ordimensions to correspond to the capacity required. Its closed top isformed with a central externally-threaded stuffing-box 2 to receive thepacking-gland 3, and its lower edge is provided with an annular flange4, by means of which it is secured to the hollow base 5 by the bolts 66.

7 represents a central tubular shaft, its upper end extending throughthe stuffing-box 2,

and on this projecting end is fulcrumed the crank-handle 8 by means ofthe bolt 9, .so as to permit a limited vertical movement of the outerend of said handle. The lower'end of the tubular shaft 7 terminates in ataper plugcock 10, which has a bearing in the valvecasing 12, which maybe formed integral with the base 5L This casing 12 is provided with aninlet-pipe 13 and an outlet-pipe 14, which terminate in a gooseneck 15for the discharge of the filtered Water.

16 represents a-radial passage in the plugcock, which is alined with theinlet-pipe 13, and it communicates with the vertical passage 17 in thetubular shaft 7, and the upper end of the passage 17 terminates in aseries of radial orifices 18 18.

19 represents an annular disk resting upon the annular shoulder 20 ofthe plug-cock', and 21 represents a packing ring or gasket to form ajoint between the disk 19 and the lower end of the filtering-cylinder22.` A similar gasket 23 is located between the upper end of saidcylinder 22 and the disk 24, which shclamped to the upper end of thecylinderby' the nut 25, engaging the threaded portion 26 of the shaft 7.4

27 represents a hood or bonnet which encompasses the upper end of theshaft above the porous cylinder, and it serves to deflect the water fromthe orifices 18 and distribute it evenly over the outside surface of thecylinder.

28 represents a radial passage in the plugcock, which is alined with theoutlet-pipe 14, and it connects with a vertical passage 29, which inturn communicates with the interior of the porous cylinder.

30 represents an air-chamber depending from the disk 24, so as to occupythe space in rthe upper end of the filtering-cylinder.

31 represents a curved plate fixed on the upper end of the outside ofthe casing 1, and it is provided with two stop-notches 32 and 33,located in the path of the outer end of the lever-handle 8. Y

34 represents a spring-pawl fixed on the upper face of the base 5, andits free end is adapted to engage a notch orrecelss` 35, formed in afiange 36, depending from and extending part way around the lower disk19, so as to permit the porous cylinder to be rotated in IOO onedirection and prevent it being rotated in the opposite direction.

37 represents the Waste-pipe, the upper end of which terminates in avalve-seat 3S, located in the base 5, and 39 represents a valve pivotedon one end of a lever 40, fulcrumed in the bracket 41, fixed to thebase. The opposite end of the lever 40 projects upwardly and into thepath of the depending iiange 36, so that in rotatingthe porous cylinderthe :Iiange 36 presses the free end of the lever 40 down, therebyraising the valve and permitting the water in the casing to escape.

41 represents a vertical shoe secured to the ends of two parallelsprings 42 42, fixed at their opposite ends to the inside wall of thecasing, and 43 represents a strip or bar of sandstone or similarabrading material held in the shoe and arranged to be held in contactwith the outer face of the porous cylinder. Ay scraper-bladev 44 ispivoted to the shoe 4l, and its edge is held in contact with thecylinder by means of the spring 45.

The operation of the filter is as follows: When the lever 8 rests in thenotch 32 in the plate 31, the feed-water is on and passes up through thetubular shaft 7, out through the orifices 13, and under the hood 27,which deflects it over the outside of the poronscylinder, through whichit passes, and compresses the air in the air-chamber 30, and if thelever 8 is now raised from the notch 32 and turned to the right thefeed-water is turned off, and the water inside of the porous cylinder isforced outwardly through the walls of the porous cylinder, and at thesame time the sandstone bar 43 and the blade 44 remove the slime orsediment from the outside of the porous cylinder, and the flange 36raises the sediment-valve 39 to allow the escape of the refuse. Thelever-handle may now be turned around and left to rest in the notch 33,in which position. both the inlet and the discharge pipe are open and acontinuous flow of filtered Water is discharged at the gooseneck-outlet.When sufficient filtered Water has been discharged at the outlet-pipe,the lever is movedforward to the notch 32, which cuts off the discharge,but leaves the inlet on. Consequently the filtered water accumulates inthe porous cylinder until the air-pressure in the air-chambercounterbalances the waterpressure in the inlet-pipe.

Having thus fully described our invention, whatwe claim as new anduseful, and desire to secure by Letters Patent of the United States,

1. A filter comprising the cylinder 1, provided With the valve-casing 12having the Water inlet and outlet in combination with the centraltubular shaft 7, provided with the radial orifices 18, and the plug-cock10 having corresponding inlet and outlet passages, the concentric porouscylinder 22 and the airchamber 30, and means, substantially as setforth, for simultaneously operating said plugcock and porous cylinder,as and for the purpose set forth.

2. A filter comprising the cylinder 1, provided With the valve-casing 12formed with the inlet 13 and the outlet 14, the retainingspring 34, andthe notched plate 31, in combination with the vspring-actuated scraper44 and abrading bar 43; the vertical tubular shaft 7 provided with theorifices 1S, the plugcock 10 fixed to the lower end of said shaft, theiianged disk 19 and the hand-lever 8, pivotally secured to said shaftand adapted to engage the notched plate, the porous cylin der 22 and theconnected air-chamber 3() removably secu red to said shaft, concentricwith the cylinder 1, substantially as described.

In testimony whereof We hereunto affix our signatures in presence of twoWitnesses.
